http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1393The method is fascinating. Also looked at other people's thinking to come out.First consider turning 0 all into-1. Then a prefix is counted and expressed in sum[i].Then the substring starting from the starting point is valid as long as the value of Sum[i] equals 0.If the substring starting point is
01 the problem of obtaining and not obtaining a backpack is actually an opportunity cost problem. If you take something, although the current value has increased for the moment, you have paid the opportunity cost. If not, the space left may be more valuable in the future. Therefore, space and value are always in conflict. Our goal is to use limited space to load the best value.
